Hi,
I have became embedded developer since 2012 and have did a lot of embedded system project for Hobbyst, Robotic, Industrial, IoT, and Military-aerospace application. I know both firmware and hardware(electronic) part, since my bachelor degree is electronic engineering.
I'm familiar with popular Microcontroller like AVR,STM32,NXP,Arduino,NRF. I also familiar with most of popular peripheral used for microcontroller like USART,SPI,I2C,DMA,ADC,DAC,RTC,Interrupt, etc. The concept are same on all microcontroller, the different are just on detailed architechture of them.
I can work with RTOS too, and I'm familiar with ChibiOS,FreeRTOS.
Let me know your problem and I will help you solve it.
We can negotiate the project delivery and cost once you tell me the detail of your project.
Best Regards,
Rijal
